Catecholamines in Blood

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • Doing physical exercise.
  • Having extreme emotional stress.
  • Having surgery, injury, or illness.
  • Taking certain medicines, such as aspirin, nitroglycerin, tricyclic antidepressants, tetracycline, theophylline, or some blood pressure medicines.
  • Using nicotine, alcohol (ethanol), or cocaine.
  • Taking nonprescription cough, cold, or sinus medicines.
  • Eating or drinking foods with caffeine.

What To Think About

  • This test is not done very often. The 24-hour urine test is better for finding high levels of catecholamines than a blood test. For more information on a catecholamine urine test, see the topic Catecholamines in Urine.
